Weaving together fascinating case histories, clear accounts of concepts and discoveries in neuroscience, and an intimate view of the suspense, excitement, and angst that color a neurologist’s days, Adam Zeman also considers what the brain’s behavior—and misbehavior—can tell us about the human self as physical system, living creature, and conscious mind. Zeman tells stories of patients with a variety of neurological disorders, some familiar (epilepsy, chronic fatigue, stroke, memory loss) and others that are relatively mysterious (narcolepsy, chronic déjà vu, compulsive fidgeting), revealing the various levels of the brain, from the atom to the mind, to explore what happens when workings at each level go awry.
